When is a surface or component clean enough?

9-10 June 2021

Online via MS Teams

When working with components and surfaces we often come across questions such as: “Is this clean?”, “How clean is it?”, and “Is that clean enough?” We ask these questions when dealing with various types of processes, including a surface that needs to be painted/plated, two parts that need to be welded together, a surface that will be used for pharmaceutical preparations, or in clean room facilities for other technical purposes. All these processes and systems depend on having a surface that is clean enough, and the consequences can be tremendous, if a product or process fails due to insufficient cleaning.

Answering these questions is, however, not as straightforward as one might first think. Cleanliness needs will vary depending on the use and location: Grease in a bearing system is expected but grease on a surface to be painted is not. Cleanliness is, therefore, often not a simple thing to either define or measure. In this seminar we will look at cleanliness issues in various types of applications and components, and participants can thereby find inspiration from other industries and research institutes. Topics such as how cleanliness can be defined, how it can be measured and how you can solve cleanliness issues will also be tackled.

Wednesday 9 June 13.00-15.30
The first afternoon will cover an overview of technical cleanliness. The focus will then shift to electronics, looking at how cleanliness affects reliability at the manufacturing stage, as well as how electronics can be cleaned following damage.

Thursday 10 June 13.00-15.50
The second afternoon will first look at cleanliness from the perspective of two specific industries: industrial manufacturing and the pharmaceutical industry. Here we will look at how cleanliness is measured and the effect cleanliness has on production and product safety.  In the second half of the afternoon we will then look at cleaning processes and cleaning methods available and their contribution to sustainability.

Target audience
The seminar is aimed at quality engineers, industrial and production technicians, design engineers, process engineers.

Technical Cleanliness – an important but complicated subject

Pär Andersson, Researcher, RISE Research Institutes of Sweden

Keeping control of cleanliness levels is a vital part of the final quality of manufactured parts and systems. Without a sufficient level of cleanliness, the system will in time get degraded or even worse break down immediately. In this presentation, Pär Andersson will go through some of the basics of technical cleanliness and how it affects real systems. He will also talk about the analyses process and what they are doing at RISE to further improve the knowledge in this area.

Pär Andersson has been working as a researcher in the area Technical Cleanliness at RISE (Research institutes of Sweden) for more than 10 years. He has started the Swedish cleanliness network CFR (Centre for Cleanliness) to improve the knowledge and cooperation between companies that is affected by technical cleanliness.

PCBA cleanliness as a means to improve humidity robustness of electronics

Rajan Ambat, Professor, DTU Mechanical Engineering

PCBA cleanliness is a key factor determining the humidity robustness of electronics due to the hygroscopic and corrosive nature of the residue. Residues on the PCBA can result from manufacturing processes as well as from applications. However, soldering process used for making PCB assembly is a main contributing factor, therefore several strategies can be followed in order to reduce the risk. This talk will comprehensively cover this issue.

Rajan Ambat is Professor in Corrosion and Surface Engineering, DTU Mechanical Engineering. For 13 years he has been manager at the Center for Electronic Corrosion and CreCon Industrial Consortium for Climatically Reliable Electronics. The CELCORR group works on all aspects of humidity effects on electronics, which leads to electrochemical failure modes and focuses on measures to improve humidity robustness such as prevention, protection, and prediction.

Techsave: We bring liquid damaged technology back to life

Jonas Vincenzo Tedde, Head of Development & founder, Techsave A/S

The concept by Techsave is to clean laptops, smartphones, and tablets in the most sustainable way possible, without any compromise regarding quality, warranty, and risk. Techsave was born by technicians with a great idea, without any commercial experience outside Denmark. In 10 years, the journey from cleaning an electronic device with a toothbrush became a fully automatic cleaning monster. The machine removes corrosion in devices by combining Nordic Swan Ecolabelled soap, water, ultra-sonic and vacuum in a patented process.

Jonas Vincenzo Tedde has previously worked with service and IT for AV Distribution A/S and is now Head of Development & founder of Techsave A/S.

Component cleanliness in an industrial manufacturing company

Ann Fenech-Andersen, Lead Specialist, Materials & Processes, Danfoss A/S

As companies strive for performance optimization of their products, component cleanliness becomes ever more important. In this presentation an overview of the challenges encountered within component cleanliness in an industrial manufacturing company will be discussed, ranging from specification to real-life troubleshooting. The presentation will be supported by real-life cases studies.

Ann Fenech-Andersen is a lead specialist at the Danfoss Technology Centre with a focus on component cleanliness, lubrication and surface treatments. Ann has a B.Sc (Hons) in Chemistry and Biology from the University of Malta and a PhD in materials science from University College London.

Development of cleaning methods and cleanliness limits in an oral solid dosage forms facility handling products with a low toxicity score

Henrik Vestergaard Frandsen, Cleaning Validation Responsible, Novo Nordisk A/S

This talk will focus on why clean equipment is important in the pharmaceutical industry, when cleaning is needed and what you should look for. How can visual inspection be used to reduce equipment sampling in production for low toxic oral products. What technologies exist to get faster results and faster release.

Henrik Vestergaard Frandsen gratuated with a M.Sc. in biotechnology from DTU in 2011. Since then, he has held various roles in cleaning validation at Novo Nordisk A/S. He is now Project manager in Oral Protein Formulation (OPF) with the primary tasks of expanding facilities and production capabilities.

Cleaning processes: Choosing the right cleaning process from evaluation of a specific part and contamination

Brian Chr. Hansen, owner and director, ABC-CLEAN Aps

The most reliable way to establish a reliable cleaning process is to start with an analysis of the component, the contamination to be removed and the required “clean enough”-result . The talk will mainly focus on the evaluation of various industrial metal parts to be cleaned, and on the suitable cleaning technologies and processes that should be taken into consideration.

Brian Chr. Hansen graduated as B.Sc. in mechanical engineering in 1997, and has since 1999 worked as an industrial cleaning specialist. He has been the director of ABC-CLEAN since 2008.

How to achieve efficient and sustainable cleaning processes

Marius Grewe, Application Engineering, Bio-Circle, Germany

The focus of the talk is on the cleaning process prior to the question of the seminar: “When is a surface or component clean enough?” covering bioengineered in-line-treatment and recirculation techniques. The talk will include a discussion on how green and sustainable cleaning processes can be implemented and even improve the satisfaction of cleaning processes until the final question: is the surface clean enough?

Marius Grewe hold a BA in Chemical Engineering from the University of Applied Science in Münster and a MSc in Materials Science from University of Paderborn. Today Marius is Application Engineer / Product Manager at Bio-Circle Surface Technology GmbH.
